BREECH-LOADlNG FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 367,089. dated J v 1881 Application filed October 8, 1586. Serial No. "315,689. (X model To all whom it may concern.- I

lie it known thatl, ALEXANDER T. 1 RO\VN, of Syracuse, county of Onondaga, in the State of New York, a citizen of the United States, have invented certain new and useful Improvements in Breech-Loading Fire-Arms,of which the following is a specification, reference being had to the accompanying drawings.

In the accompanying drawings, Figure 1 represents a side elevation ofthe gun closed, with the liring-pin of'the third barrel in position to be operated by the hammer; Fig. 2, a like view thereof, with the third barrel discharged; Fig. 3, alike view thereof, with the third barrel discharged and the gun broken down; Fig. 4, alongitudinal vertical section of Fig. 1. Fig. is alike View of Fig. 2; Fig. 6, a like view of Fig. 3; Fig. 7, a transverse seetion of the barrels; Fig. 8, a transverse section of the breech-block in front of the hammers, showing third-barrel tiring-pin in position for firing; Fig. 9, a like view showing this tiring-pin out of position; Fig. 10, a

. longitudinal section of the barrel and breech on the line of the centcrot' the third barrel; Fignl'l, a rear elevation of the barrel removed from the stock; Fig. 12, a top plan view of breech block and frame, Fig. 13, a front elevation of breech block and frame; Fig. 14, a vertical longitudinal section (enlarged) of the gun broken down; Fig. 15, a bottom plan view of the barrels; Fig. 16, a plan view of the inner face of the foreend, showing the fore-end fastening; Fig. .17, a detail of the third-barrel iiring-pin; Fig. 18, an elevation of the hammer, showing the tiring-notch in its inner face which operates the third-barrel firing-pin; Fig. 19, a front elevation of the hammer.

Like letters indicate like parts wherever they occur.

My invention relates more especially to three-barrclul guns, although some of its distinctive features are applicable to other st. lcs ofbreech-totalinglircarms. .lhescdistinctive features relate to the following points, viz: first, the firing mechanism; second. the forecnd fastening; third, the shcli-ciecting mechanism. There are also other special features of const ruction and operation, as will behcrc inafter fnll described, and specifically set forth in the claims annexed.

The objects of my invention are to increase the durability and efficiency of the firearm, as well as the ease of manipulation. It is constructed as follows:

A is the stock.

13 B are the shot-barrels, having the rideoarrel 0 attached thereto and beneath and between them.

D is the breech-block, mortised to receive the extension-rib 1, and, in general, the whole mechanism for locking the barrels by a rotary lock engaging with the mortiscs in the extension is the same as has been previously the subject of Letters Patent granted to me, with one single exception-win, the addition of the forwardly-pro ecting stud 2 near the bottom of the action-post3and in the frontside thereof, and therefore I will not enter into a detailed description of the barrel-locking mechanism.

E is the frame.

F is the fore-end.

H II are thchammers, which are of ordinary construction, with the exception that in the front inner edge of the left-hand one i cut the groove 4. at about the point shown in Fig. 18, extending upward in a nearly-vertical line, and thence turning by substantially a right angle out to the edge, thus forming the shout der 5. This groove 4, with the shoulder 5, is the first element of the firing mechanism of the rifle-barrel. The second element of this mechanism consists of the firingshaft (i, which is inserted transversely across and through the breech a little forward of the action-post 3. This firing-shaft consists of a rod of metal provided at one end with a cylindrical head, 7, having in its outer edge a groove, 8, shout dcred at 9, a central st-ud,jt0, projecting backward and horizontally, and betweonthe head and stud a downward lug, 11, having a flat front face, all substantially as shown in Fig. l7; and in Fig. to I show notches 12 in the edge of this shaft, and a spring-pin, 13, inserted into the breech, the point of which engages with thcsc notches, and this pin and the notches operate to hold the shaft either in or out of gear with reference .to the firing-pin llof the. rifle -b:rrrel. 'l'his firingpin is constructed with a head and forward point, and is inserted into the breech at about the point shown in the drawings. The rear end of this head is cut away on the upper edge, leavinga shoulder, 15. This firing-pin constitutes the third element of the ride-firing mechanism. This mechanism operates as follows:' When the firing-shaft is in the position shown in Fig. 8, the lug 11 is in engagement with the.

shoulder 1 -5 of the firing-pin, and then when i the left-hand trigger is pulled that hammer is released and the shoulder 5-011 the hammer strikes against the shoulder 9 in-th'e head of the firing-shaft and partially rotates the shaft. When this rotation begihs, it throws the lug 11 forward, and this drives the firi ngpin forward quickly against thecap of therifle-shell. Then when the gun is opened the rotation of the action-post throws the stud 2 againstihe lower end of the pivoted. shifter 16, mounted upon the back face of the breech, and its upper end, encountering'the stud 10 uponthe fir- ;ingsshaft, throws this shaft over towardthe right and into the position shown in Fig.9,

" -practicall'ydisengaging the lug 11 from the firing-pin and leaving .the left-hand hammer free to strike the shot-barrel firing-pin 17 on that side, the head of the firing-shaft being drawn back out of the way, and the springipin 13 then engages with the inner notch, 1 2. *In this position the rifle-barrel cannot be fired nntilthe 1ug11 is again thrown into engagement with the ride firing pin, and this re-engag'ement is effected by pressing the finger against the projecting end of the firingshaft upon the right and pushing the'shaft over to the left until they are again in the position shown in Fig. 8, and'so long as the parts are in the posit-ion shown in Fig. 9 the rotation of the action-post does not affect the shifter 16, because the stud 2 does not touch it or move it. i

is constructed as follows, (see Figs. 7 and 16:)

At the proper point in the fore-endthe rifletinga portion of the rims of the respective.

extractor. The extractor consists of a body,

in this instance provided with threefaces, fitshells, the lower and central one relating to the rifle-shell. This extractor-body is mou nted upon two rods, one on each side-of the rifle barrel, extending forward to the hinge be tween the fore-end and the frame in the ordinary manner. In the center of this body, in

, its outer face and extending upward from the rifle shell face, I cut a groove, in which my ejector fits loosely. This groove also extends upward fron the extractor in the rear end of the barrels'and opens intoalongitudi-nal chan- The second feature (the fore-endfastening) nel, 22, cut'inthe bottom of the extension-rib,

across which channel I place thepin 23. ,The' ejector is pivoted at 24 in the extractor and its'up per end extends upward into the chan-' nel 22 forward of the pin 23. The lower end of this ejector is provided with .a 11p of the same form as the edge of the'extractor ad acent thereto. This operates as follows: As the gun is broken down the extractor starts out, carrying the shells of all three barrels with it, and all of the shells move in like degree until just before the stroke of'the extractor is. finished the Upperend of the ejector encounters the pin 23 and the ejector is tilted, the lower end carrying the rifle-shell head out beyond and away from the extractor until its shells. 'This makes it more convenient to remove the riflc-shell with thefingers. 'I can also adapt this same principle to adouble gun, throwing both shells out beyond the stroke of the extractor,'using an ejector for each barrel, or using one with a central body and a side arm for each barrel.

head is farther out than the heads of the shot-' The next novel feature of my invention re lates to, the construction of the frame, the

hinge-pin, and the lug under the barrels, which enters the frame. In this construc:

.tion the mortise adjacent to the breech-face and forward nearly to the check-hook is of.

ordinary 'sizesay three --eighths of an inch,

out the mortise, for. the whole length. of that part which does cut through the frame clear as at 25this portion not extending through l the frame Forward of this port-ion I'wldenout to the front of the frame, as at 26, say;

to a width of three-fourthsof an inch. This enables me to enlarge the lug 27 as to that.

part which'fits the mortise 26, giving a stiffer I support for the barrels in their connection bythe lug to the frame. This enlargement of the lnganortise in the frame also enables me to use a heavier hinge-pin, 28, at least as to its diameter. This hinge-pin is centrally between the arms of the frame provided with a trans verse circular slot, 29, to receive theride-barre]. Thisslot extends out toward the arms of the frame, but not quite to them, leaving the shoulders 30 to supportthe barrels.

The remainder of this fire-arm is of ordinary construction, and I do not consider needs a specific description. j

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a three-barreled gun, the rifle-firing mechanism'consisting of a hammer provided witha shouldered recess in its edge, a firing-- shaft extending transversely of the frame and provided with a downward lug, and a head having also a shouldered recess, and the firing pin in linejof engagement with said shaft, constructed and operating together'substantially as described.

2.111 a fire-arm, the releasing mechanism consisting of the action-post provided with a stud, the pivoted shifter engaged thereby, and

the'stud upon the firing-shaft on which said shifter bears, all combined, constructed, and

operating together substantially as sh own and projection in position to bear on said pin, a

hammer, and mechanism, substantially as de scribed, by-wliich said shaft may be shifted to throw it into or out of engagement with the hammer, substantially as described.

5. In combination with the firing-pin and hammer of a hreeclrloiuling gun, a firing-shaft mounted in the frame to have a movement into or out of operative engagement with said pin and hammer, and stops on said shaft to limit its movement, substantially as described.

(5. The combinatiomin a breech-loading gun, of alongitndi nally-moving eXtraetor,anejector pivoted in the extractor, and a stop in the line of movementot'oneend of the ejector, whereby the backward movement of the extractor actuates the ejector, substantially as described.

7. In abreeclrloading fire-arm, a frame provided with a mortise and a mortise enlarge ment, in combination with a barrel-lug fitting said mortise andenlargement, substantially as shown and described.

8. In a breakdown gun, a frame having central mortise, a transverse pin extending across the frame, said pin being grooved across its upper face and having shoulders adjacent to the groove projecting slightly beyond the sides of the frame, in combination with apair of barrels pivoted to break down on the stock, substantially as described.

9. In combination with a pair of gun-barrels secured together side by side and having a longitudinal rib under the same, a fore-end stock having a longitudinal groovein its upper face, and a pair of springarms in said groove, having sufficient play therein to clasp and unclasp the rib on the barrels, substantially as described.

In witness whereof I have hereunto set my hand this 29th day of September, 1886.
